方法一：

int main(void)
{
    int a = 0, b = 0;
    float c = 0;
    scanf("%d %d", &a, &b);
    c=(float)b / 100;//将b强制转化为float
    c *= c;
    c = a /c;
    printf("%0.2f", c);//%0.2f意味着小数点后保持两位
    //后续我会发一个帖子，详细介绍C语言——%d,%-7d,%7d,%07d的区别，到时候可以点我主页看
    return 0;
}

方法二：

 
 
int main()
{
    int weight = 0;
    int height = 0;
    double bmi = 0.0;
    scanf("%d%d", &weight, &height);
    bmi = weight/((double)height*height/10000);
    printf("%.2lf\n", bmi);
    return 0;
}
